. SHIPS BLOCK.

Specification of Letters Patent No. 10,688, dated Mai'ch 28, 1854.

section on line m a: of Fig. 2 perpendicular to the axis of the sheaves.

Similar letters denote the same part.

My invention consists in constructing ships blocks with a shell of cast, malleable or wrought iron, or any other suitable metal into which are fitted wooden cheeks and the sheaves, the whole constructed and arranged as will be hereafter described.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation. In the drawings a; a are the cheeks b the top, and c the bottom of the shell made of cast, wrought or malleable iron, or of composition or other suitable metal, the thickness of the cheeks to be determined by the size of the block. Within the metallic shell is the wooden lining cZ made in any suitable held by the pin 6; and if it be desired to have a ring at the bottom of the block, the hook h may be provided with a long shank which shall pass entirely through the block, be held by the pin 6 and have the ring attached to its protruding extremity. Or, the ring may be provided with ashank which shallbe fastened in the bottom of the block as above described for the shank s.

This block is far'lighter than any now in use, is much neater in appearance and through the block. The shank may pass down below the center of the block and be possessed of'grea ter durability. The wooden lining will prevent the wear of rope which renders metal block objectionable, and can readily be replaced when rotted and Worn out. Another great object gained by the use of this block is its exemption from the splitting so destructive to all other blocks, particularly when used in warm climates.

As regards the expense of this improved block; it is as cheap as ordinary iron or rope strapped wooden blocks, and if the duration of the several articles be considered, is far more economical than any block now in use. WVhat I claim as my lnventlon and deslre nesses.
